With the development of pulsed power technology, pulsed power equipment requires metallized capacitor with high energy density and large discharging current. Large discharging current makes leading wire pulling form the capacitor, or breaking the leading wire. This paper aims to calculate the electodynamic forces of metallized capacitor’s leading wire under DC, AC and transient state through ANSYS. The results show that electrodynamic force is smaller with annular leading wire, electrodynamic force increase with the frequency increasing under transient current, electrodynamic force increase with the rising time decreasing.
